T0 aZZ whom it may concern:

Be it known that I, HARRY C. Boson- MANN, a citizen of the United States, and a resident of Indianapolis, county of 'Man ion, and Eitate of Indiana, have invented a certain new a d useful AcetylenaGas Gem orator; and I do hereby declare that the following is afull,.clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to prov de a satisfactory arrangement .for providing acetylene gas generators with a reserve charge of carbid. Effort has been made by others heretofore to arrange such generators to accomplish said object, but means for operating the same has been arranged so as to extend through the casing or wall of the generating chamber and thus create a leak or some other flaw or imperfection. In others the operation has been by means of le vers extending below the waterline of the generating chamber and then up so as to trip the reserve hopperfrom beneath and,

therefore, is complicated.

The nature of the invention will be understood from the accompanying drawings and the following description and claims.

in the drawings, Figure l is a central vertical section through the upper part of an acetylene gas generator in operating condi tion, the lower part being broken away. Fig. 2 is a similar section of the carbid chamber with the reserve feed chamber open. Fig. 3 is a plan view of Fig. 2 with the door of the reserve feed chamber closed;

There is shown herein a generator chamber with a rigidly secured top 11 with a handle 12 whereby the same can be turned if desired. A carbid chamber 13 is supported within the generating chamber 10 by any suitable means such as the support 14, and it has an out-let closed by a valve 15, the particular construction of which is immaterial to this invention. Upon the carbid chamber there is a chamber 17 with a door or bot;

tom 18 hinged at 19, and said door is held closed, as shown in Fig. I, by a latch 20. This latch has a lower arm which engages and holds a door or the bottom 18 closed, and a straight vertical portion is mounted in the top of the carbid chamber so that the latch is horizontally oscillatory and-it is actuated or oscillated by having an upper horizontal arm adapted to be engaged byia rod or projection 21 extending down from the top 11 of the generating chamber, so thatwhen the said top 11 is turned somewhat, the rod 21 will engage and actuate the latch and release the door- 18 to permit the carbid in the chamber 17 to drop down in the carbid chamber.

in operation when. the carbid in the car-, bid chamber 13.has been exhausted and for any reason-it is desired that the device opcrate a little longer before recharging, the

top 11 of the generating chamber is turned somewhat by the handle 12 so as to release the latch from the door 18 of the reserve chamber. This will discharge the contents of that chamber into the carbid chamber.

With the foregoing arrangement, the reserve carbid chamber is controlled from the exterior, and not by any means extending.

through or operable through the wall of the, generator chamber, so that the Wall of said generating chamber may be imperforate. Also with this arrangement, the door of the reserve carbid-chamber or holder can be raised or removed so as to permit a filling of the main carbid chamber through the aperture connecting the two carbid chambers. The advantages of this arrangement are that a very large hole is offered through which the main chamber can be filled, and, furthermore, the assurance that the reserve chamber must of necessity contain nothing but fresh carbid.

The invention is not limited to the particular construction of the main or reserve carbid chambers and by generating chamber herein is meant all parts to which the gas when generated has direct access, substantially as herein set forth.

berated by the movable part of the generating chamber for releasing the car-bid from the W 1 reserve carbid holder.

3. In an acetylene gas generator, a generating chamber having a movable top, a main carbid chamber Within said generating chamber, a reserve carbid holder on top of and in communication with the main carbid chamber, and means operated by the rotation of said movable top for releasing the carbid from the reserve-carbid holder.

' 4:, In an acetylene gas generator, a gencrating chamber With-a movable top, a main carbid chamber Within said generating cham her, a reserve carbid holder on the top of said main carbid chamber and With a movabledoor therefor, a latch for holding the door closed, and means operable by a movable part of the generating chamber for actuat ing said latch and releasing the door of the reserve carbid holder.

5. In an acetylene gas generator, a generating chamber With'a movable top, a main. carbid chamber Within said generating chamber, a reserve carbid holder on the top meaore of said main carbid chamber and with a movable door therefor, a. latchin the top of the main carbid chamber for holding said door closed, and a projection from a movable part' of the generating chamber for operating said latch to release said door of the reserve carbid holder.

6. In an acetylene gas generator, a main car-bid chamber with a permanently closed top, a reserve carbid holder in saidtop in communication with the main carbidchamher and provided with a movablecdoor in the bottom thereof for closing said communication, and means for opening said door, whereby the main carbid chamber can be charged only through said reserve carbid holder and therefore a fresh reserve charge of carbid is absolutely assured.

In Witness whereof I have'herennto affixed my signature 'in the presence Of'the Witnesses herein named.
